Sigourney Weaver believes in aliens.
The actress - who is most famous for playing Ellen Ripley, the heroine who Battles the deadly, acid-blooded xenomorphs in the 'Alien' movie franchise - is convinced extraterrestrials exist and believes the US government actively suppresses information about UFOs
She told German magazine TV Spielfilm: "We are not alone in the universe. I think there's a department in our (the US) government which is exclusively dedicated to quashing reports about aliens. And that's so unfair. It would be nice if we weren't just able to read about it in the tabloids."
He said: "I think there are extraterrestrial life forms in the cosmos. I think it's more likely than not. The cosmos is a pretty big place."
Robbie Williams has claimed to have had several close encounters of the third kind in the last few years, including being visited by spaceships on three occasions.
